Universal Coordinated Time UTC – ZULU is a 24 hour clock. During an eruption, if the wind is from the east at 10,000 feet (outflow), the tephra will fall on Vancouver, Canada in about an hour. If the Kulshan Wind is from the west (inflow) the tephra will fall on Merritt, BC in about 40 minutes. There are extremes in preparedness, of course. As a basis of my work I use the 2015 Profile of Earthquake Risk in the District of North Vancouver by Earthquake Canada, wherein they state that there is 30% chance of a M7.3 in the middle of the Salish Sea, say between North Vancouver, Nanaimo and Victoria, in the next 50 years, that will bring down 839 buildings, just among the 80,000 residents in the District of North Vancouver.

Lahar / Debris Flow Potential from 3,286 m (10,781 ft), Kulshan Stratovolcano© / Mount Baker Stratovolcano© - 13 July '11: Mer de Glace Debris Flow

This might be what a lahar / debris flow  coming down from the glaciated ice sheet on top of 3,286 m (10,781 ft) Mount Baker Stratovolcano.  It would likely look like:

The two summits are located on the west ridge of the Aiguille Verte (4,122 m) and are connected to each other by the Brèche du Dru(3,697 m). The north face of the Petit Dru is considered one of the six great north faces of the Alps.

Significantly condensed; debris flow continued for over 45 minutes.  [Wikipedia: TThe mountain's highest summit is Aiguille du Dru (also the Dru or the Drus; French, Les Drus) is a mountain in the Mont Blanc massif in the French Alps. It is situated to the east of the village of Les Praz in the Chamonix valley. "Aiguille" means "needle" in French.
  • Grande Aiguille du Dru (or the Grand Dru) 3,754 m
Another, slightly lower sub-summit is:
  • Petite Aiguille du Dru (or the Petit Dru) 3,733 m.
The southwest "Bonatti" pillar and its eponymous climbing route were destroyed in a 2005 rock fall.[2][3]


At 3,286 m (10,781 ft), Mount Baker Stratovolcano is the third-highest mountain in Washington and the fifth-highest in the Cascade Range, if Little Tahoma Peak, a sub-peak of Mount Rainier, and Shastina, a sub-peak of Mount Shasta, are not counted.
